Filed: 1917-06-16
Abstract: 116,169. Pearce, W. H. June 16, 1917. Draught-inducers.-Locomotives and other engines of the type in which the exhaust steam. passes through a blast-pipe into the smoke-box to create a draught have pivoted disks arranged over tne end of the blast-pipe to prevent ashes &c. passing to the cylinders when the engine is running without steam. The blast-pipe a arranged in the smoke-box below the chimney a is normally closed bv a disk k carried on a lever j. Pressure of steam in the pipe a when the engine is working lifts the disk h nearly to the upright position, from which it tends to return under the action of gravity. An auxiliary valve m carried by the disk permits escape of steam under small pressure, the flanged sides k<1> of the disk k ensuring that it is directed towards the chimney b. A cylinder f<2>, supplied with steam when the regulator valve is opened to admit steam to the main cylinders, carries a piston f<1> operating the damper d<1> of the superheater c, the damper being arranged to raise the disk k when the steam is turned on, but to allow automatic rise of the disk if the damper-operating gear is out of order. If no superheater is provided, the piston f<1> may bear directly against an arm on the lever j. The piston may be arranged to operate link-work to move the disk laterally front the tube a, the disk being pivoted to rise automatically under direct steam pressure. The hinged disk may be operated directly from the regulator handle through suitable link-work.

Class 142(2) A leno weave is formed at each side of a gap left in the warp in a circular loom, the wefts extending across the gap being cut to produce a flat fabric. The leno weave is produced by doup healds comprising members 10, 14, 15. Thermosetting resin or rubber solution may be applied to the selvedges. The edges may be strengthened by increasing the warp density. To prevent undue stressing of the yarn 11 forming the leno weave, the yarn 11 has an individual spring tension compensator. A projection 27 may be provided on the weaving ring 8 to ensure even spacing of the selvedges 36, 37. To prevent the selvedges being dragged round by the shuttles, an arm 29 (Fig. 2) has a beak 28 engaging the gap in the warp. A shoe 34 resting on the warp is lifted by each shuttle and raises the arm whilst the shuttle is passing. The beak may inject the adhesive into the selvedges each time it is lowered. The arm and the members 14, 15, which latter are shown connected to healds 3, 4 respectively, can be operated by cams driven from the main motor. The fabric may be a plain weave or a 1:2 or 2:2 twill.

Abstract: 943,989. Hydraulic brakes; valves. BENDIX CORPORATION. March 9, 1962 [March 27, 1961], No. 9235/62. Headings F2F and F2V. A deceleration sensing valve for use in a vehicle hydraulic master cylinder braking system comprises a valve body 20 with a chamber 28 inclined vertically in a forward direction and extending in the line of motion of the vehicle, a partition wall 32 across the chamber having an opening therethrough controlled by a spring loaded poppet valve 46 which is normally kept open by the weight of a ball 50, an inlet port 42 on the front side of the partition member being connected to one of the sets of front or rear wheel brake cylinders. In operation, the master cylinder forces fluid through the inlet port 40, through the open valve 46 and outlet port 42 to the rear wheel brake cylinders C while at the same time forcing fluid through the outlet port 44 to the front wheel brake cylinders B. As the pressure to the front and rear brake cylinders increases, the deceleration of the vehicle also increases until the ball 50 is caused to roll up the sidewalls 24 of the chamber 28 to allow the poppet valve 46 to close. When this happens, no further increase in pressure is produced in the rear wheel brake cylinders C and any further increase in pressure from the master cylinder will flow directly to the front wheel brake cylinders B through the port 44. To allow for drum expansion due to heat during a severe stop, an expansible chamber D is provided controlled by a spring-loaded piston 62. Reference has been directed by the Comptroller to Specification 900,999.
